Update to apply the changes to the SonicWALL. Now that you have enabled Bandwidth
Management, you can begin configuring Rules to use bandwidth management.
See Bandwidth Manage ment at the en d in th is sec tion f or mor e inf ormat ion Soni cWALL ’s Ba ndwi dth
Management feature s.
TIP! Traffic inbound from the WAN to the LAN/DM Z based on a Rule using bandwidth management
is allowed as if there is no bandwidth management in place. However, outbound traffic (reply
packets) for traffic associ ated with an inb ound Rule is ma naged based on the conf ig ura tio n for that
Rule.
DMZ/WorkPort Link Se tti n g s
Specifies the speed and duplex mode of the Ethernet connection to the DMZ/WorkPort link. The
default selection is Auto Negotiate because the Ethernet links automatically negotiate the speed
and duplex mode of the Ethernet connection. The other choice, Force, with lists for speed and
duplex, should be used only if yo ur E therne t c ard al so f orces thes e se ttings. You mu st fo rce f rom
both sides of your connection to enable this setting.
LAN/HomePort Link Se tt in g s
Specifies the speed and duplex mode of the Ethernet connection to the LAN or HomePort link. The
default selection is Auto Negotiate because the Ethernet links automatically negotiate the speed
and duplex mode of the Ethernet connection. The other choice, Force, with lists for speed and
duplex, should be used only if yo ur E therne t c ard al so f orces thes e se ttings. You mu st fo rce f rom
both sides of your connection to enable this setting.
Proxy Management workstation ethernet address on WAN
If you are managing the Ethernet connection fr om the LAN side of your netw ork, this check box can
be selected. The SonicWALL appliance takes the Ethernet address of the computer managing the
SonicWALL appliance and proxies that address onto the WAN port of the SonicWALL. If you are not
managing the SonicWALL appliance from the LAN side, the firmware looks for a random computer
on the LAN creating a lengthy search process.
MTU Settings
A network administrator may set the MTU (Maximum Transmission Unit) allowed over a packet or
frame-based network such as TCP/IP. If the MTU size is too large, i t may r equire m ore transmis sions
if the packet encounters a r outer u nable t o hand le a larg er pack et. If the pack et siz e is to o small , this
could result in more packet header overhead and more acknowledgements that have to sent and
processed.
The default value is 1500 oc tets b ased o n th e Et hernet sta ndar d M TU. T he min imu m valu e th at c an
be set is 68. Decreasing the packet size may improve the performance of the network.
